GREASE GUM-FILLER, I

Application filed July 15,

timeit is customary to roll the grease gun as close to a barrel of grease as possibleand then remove the grease from the barrel by a scoop, and in turn placing the same in the grease gun. This is a very laborious undertaking and requires the constant attention of an attendant. In my invention, the grease gun will be filled without resorting to a human agency except to place the grease gun in position and operate a means for controlling the filling of the grease gun. The grease used being a viscous solid presents a problem in dispensing and handling that is not present in other commodities. After experiencing great dificulty in the handling of grease and laboriously filling the gun by hand which was the recognized method, it occurred to me that in spite of the viscous nature of the grease that it could be fed into a gun under its own weight aided by gravity. I experimented and found my theory to be correct, provided the cross sectional area of the opening in the dispenser was large enough to overcome the surface tension of the grease.

V This surface tension, of course, varied with various greases, but worked efiiciently where more than half of the surface area of the.

bottom of the container was removed. I further found that not only would the viscous 7 solid feed out of the container, but it would feed itself entirely out so thatthere would be little or no waste in the container and be no necessity for plungers or other mechanical contrivances to remove the grease from the container. I did find, however, that this movement was greatly facilitated by making to provide means.

Referring to the drawings in which similar reference characters refer. to similar parts throughout the several viewsz Numeral 8 designatesa supportingstruc- 904 ture, on which is placed a barrel of grease 9," Beneath thebarrel of grease9 is placed/a grease gun 10. The grease gun 10 is support-i ed by a platform 11, which in turn has roll 7 p 7 ers or wheels 12. A funnel 13 issecuredto 1' the barrel 9,'by means of boltsjl l, openings 15 being: formed in aflangeltl'around the edge of the funnel 13, so as to coincide with holes in'thebarrel 9 fromwhichi the cover 7 plate hasbeen removedu The-neck portion 18 of the funnel 13 has a'slide valve housing 19, in which is mounted a cut-off slide valve v 20. The slide valve 20 has a stop member 21 which limits the opening of the valve 20 and is removable so as to permit the withdrawing of the slide valve 20 for repacking purposes. The outer end has a turned up flange 22, which maybe used as a hand hold for facili- 1 tating the operation of the valve 20. Below I 1 the slide valve housing 19 is formed a collar 23, having an inner wall 24:. Between the collar 23 and the'inner wall 24, is -placed a packing 25. 'At the top of the inner wall 24 I is formed a semi-circular flange 26 in the form of a lip to form a rest and valve seat for and the cover plate removed therefrom.

The funnel 13 is then bolted in place andthe barrelQ-turned so that the funnel will bediirected downwardly. The grease gun 10 is then rolled intoplace beneath the funnel 13,

"acts as a stop and support for the collar 23.

depending below the upper part of said framework, a collar depending from the lower end of said funnel and adapted toextend into the neck of a receptacle, a semicircular supporting flange extending into the funnel at the intersection of said collar and funnel, said funnel being slotted on the side oppositeto said flange and above said flange,

and a valve plate slidable through said slot into and out ofsupported contact with said I flange. V

In testimony whereof I atfi aw ignature.

The grease gun 10 will then be removed and rolled away to the de- "sired point of use or left in position and grease dispensed beneath the barrel.

By the use of my grease filler, no grease is 5 lost and I have found the same to be a great time andlabor saver over the old methods of 59 lil'linggrease guns. Byusing packing in the manner shown in connection with my struc- Him, I find that practically no grease is lost and further that there is very little wear and tearon the apparatus. 5 Obviously, Idonot intend to limit myself tothe specific structure shown anddescribed 1 herein, but include other structures which invention. a 60 What I claim as-n'ew'and novel is:
